NR-15 and automotive painting: Reducing hazardous working conditions.

26/05/2026

Compliance with NR-15 in automotive industrial painting This is a crucial factor for companies seeking to protect the health of their employees and avoid labor liabilities. Daily exposure to paints, varnishes, and solvents can generate serious risks if tolerance limits are not respected. This practical guide addresses the essential steps for regulatory compliance, focusing on reducing hazardous conditions and implementing a safe and productive work environment.

What does NR-15 say about the hazardous working conditions of paint operators?

THE NR-15 establishes the tolerance limits. for chemical and physical agents in the workplace. In the automotive sector, the focus is on Annex 11, which deals with hydrocarbons and other carbon compounds present in solvents. The activity is considered unhealthy when habitual exposure exceeds permitted levels, requiring the payment of an additional hazard allowance to the operator.

To formalize this condition, it is essential to draw up a document. Technical report on hazardous working conditions for automotive painting.. This document, issued by a safety engineer or occupational physician, substantiates environmental measurements and guides the necessary corrective measures. Without an up-to-date report, the company is vulnerable to fines and lawsuits.

How can we reduce unhealthy working conditions in practice?

Reducing hazardous working conditions should follow a risk control hierarchy, prioritizing engineering solutions before other measures. Personal protective equipment (PPEs).

Ventilation and exhaust in paint booths

The implementation of best practices for ventilation and exhaust This is the most effective measure. Enclosed paint booths, with properly sized airflow and high-efficiency filters, These devices drastically reduce the concentration of vapors and mists in the painter's breathing zone. It is essential to regularly monitor air velocity and filter integrity to avoid "dead zones" where solvents can accumulate.

Controlling exposure to solvents

In addition to infrastructure, the choice of high-efficiency equipment, such as paint guns with advanced atomization technology, it contributes to the reduction of overspray. Administrative measures, such as rigorous organization of the environment (organizing a preparation room, for example), are also crucial to keeping exposure levels below critical limits.

Essential PPE for painting operators according to NR-15.

Even with efficient collective controls, the use of Appropriate PPE for automotive painting It is mandatory. The main items include:

Respirators with chemical filters: Specifically designed for organic vapors and with tested seals;

Solvent-resistant gloves: Nitrile or chemical-specific models, preventing rapid degradation;

Waterproof overalls and facial protection: To avoid skin contact with mists and splashes.

Practical training on the use, adjustment, and sanitization of this equipment is vital to ensure that protection is real and not just on paper.

NR-15 Compliance Checklist

To ensure your operation is always up-to-date, use a Compliance checklist for automotive industrial painting.:

Preventive maintenance of the exhaust system and filter replacement recorded;
Completed PPE (Personal Protective Equipment) records and documented safety training;
Warning signs and proper labeling of chemical products.
